The game of Deflexion
involves abstract strategy similar in process to the game of chess,
wherein players take alternate turns to move their pieces over the board
before firing a laser, the path of which is determined by positioning
mirrored sides on the playing pieces.

If a piece is struck by the laser on one of its non-mirrored sides, then
it is eliminated.

To begin, each player has 14 Egyptian-themed pieces arranged in one of the
opening set-up configurations, with a laser set into the furthest right
hand column as the player faces the board.

The aim of Deflexion is to try and position the playing pieces in such a
way that the laser beam reflects onto the opposing Pharaoh thereby
destroying it, but at the same time each player must devise a strategy to
protect their own Pharaoh from being struck. A player can choose to either
move a piece one square in any direction on each turn, or rotate a playing
piece by 90 degrees in either a clockwise or a counterclockwise direction.
After each move that player then fires their laser and any pieces which
are struck on a non-mirrored side are eliminated and removed from play.

The Pharaoh is the most important piece, similar to the King in a game of
chess as it is both relatively weak and rarely moved unless under attack.
If it is struck by the laser then it is destroyed and its owner has lost
the game.

Opposing players have two Djeds. These are larger pieces used for
attacking and defending. They have two mirrors, which makes them
versatile, but even though they cannot eliminated from the game they can
be used against their owner. They can also change places with other
adjacent pieces like an obelisk or a pyramid, no matter their color.

Each player has seven Pyramid pieces, but each one has only a single
diagonal mirror on one surface. If a Pyramid is hit by the laser on a
non-mirrored side, then it is eliminated and removed from the board. This
means that while they are excellent for deflecting lasers they can also
become vulnerable.

Obelisks are shaped like large pillars and have no mirrored sides. To be
hit by the laser is to be eliminated, therefore Obelisks are used for
sacrificing in tight strategies. At the start of the game, opponents have
two stacks of two Obelisks each, and though they can be unstacked and
re-stacked with strategy as the game progresses, if one is hit when it is
stacked, then only the top Obelisk is removed from the board.

Deflexion underwent a name change to 'Khet' in 2006, and though the same
rules remain the opposing colors changed from gold/silver to red/silver
and a piece called The Eye of Horus was introduced as a means for
splitting the laser beam's directionality.

A second level, called the 'Tower of Kadesh' was added to the game in 2008
giving a three dimensional expansion to the field of play.
